AsleepAtTheS...	Date: January 24, 2005 @ 6:26 PM Does anyone use them? I find them great for creative ways to record/reinforce. ie...attaching one to a sheet of aluminium foil, which turns the al foil into a sort of large diaphragm....or simply affixing to acoustic instruments turning them into electric instruments. If you don't know what they look like...look here: http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&category=15198&item=3777097639&rd=1&ssPageName=WDVW

Tone is an issue with these. There is a commercial one called a Bottle Cap. I've made one using a piezo buzzer. Also, you'll likely find that you get feedback problems in a live situation because they are exposed. Not saying that there are no applications for this. In a studio we used large (4" x 4")contact mics to get room sound when micing drums. I just don't particularly think they are usefull for all applications.
FitzInStereo	Date: March 12, 2005 @ 2:20 PM I've got a bottle cap for electrifying my violin...it works pretty well. I'm trying to design my own right now, too. Anybody have any idea of how to possibly shield/insulate it to cut down on the crazy feedback in live applications?
hueseph	Date: March 13, 2005 @ 1:40 AM There's really not much you can do. Even with bridge transduecers you will have feedback problems. If you made a contact mic with a sliver of a peizo transducer and mounted it under the bridge, you might luck out that there would be some phase cancellation of the feedback but I doubt it. The best thing is a good parametric eq with a good adjustable "q" setting. Behringer makes what they call a feedback destroyer which basically is an automatic notch filter. I can't say what the quality of these is but it's worth a shot. They're quite inexpensive. (around $150.00 CDN).
